To validate that the IPv6 network is configured correctly for HP Smart Update Manager support, you must verify the following based on your operating system version.
net use *
\\<ipv6-address>.ipv6-literal.net\admin$
/user:<username>
net use *
\\fec0::2.ipv6-literal.net\admin$ /user:administrator
You might need to provide the password if you use a user name that is different from the one you used to log in to the local system. All network shares require the use of the .ipv6-literal.net name string to be properly configured by Windows®. For more information about accessing IPv6, see the Microsoft® Knowledge Base article.
After you validate you can access the admin$ share on the remote target server, HP Smart Update Manager works unless there are other network or hardware issues.
